FEED FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No.'276,253, dated April 24, 1883. Application filed May 15, 1882. (No model.)

useful Improvements in Work-Feeds for Sewing-Machines, &c.; and I do hereby declare that the following is a full, clear, and exact description thereof. I

My invention relates ,to the work-feeds and adjacent parts of sewing-machines, and is in part an improvement on the devices patented to me January 6, 1880, and reissued August; 16,1881, being especiallyadapted for use in connection with the cording attachment described and claimed in said patent and reissue.

In the drawings, Figure 1 is a perspective view of a portion of a sewing machine table, showingthe feed, presser-foot, needle, and cording attachment in proper relative positions. Fig. 2 is a central vertical section of afeed-wheel embodying my invention and Fig. 3 is a perspective of an ordinary drop-feed, likewise embodying my improvement.

A represents the presser-foot, which may be either flat on its under surface, as here shown, or grooved, as shown and claimed in my patent and reissue above referred to. Immediately below this foot is located the feed B, which may be of any ordinary construction, such as the wheel shown in Fig. 2, or the dropfeed shown in Fig. 3, with the exception that the said feed is provided on its bearingsurface with the semicircular groove D. This groove is furnished with the points or projections common to work-feeds ofall descriptions, audit is to be distinctly understood that the particular form of feed is immaterial, so long as it is provided with the said groove D.

O is my cording attachment, described in detail and claimed in my said patent, and which needs, therefore, only a brief description here. It is made in two parts, one part consisting of a lower plate of metal, bent backward at one end over a curved surface to form a passage for the reception of the cord and covering-strip, while the other part consists of a shorter plate, of the same width as the lower plate, bent up near one end atless than a right angle and straightened again,this raised portion being provided with a W- shaped strip of metal forming grooves and a tongue, all as described in detail in my said patent, and as shown in my present drawings, the two parts of the cording attachment being held together by a suitable loop and secured to the sewingmachine table by a set-screw, as shown. The fabrics, cord, and covering-strip are disposed in this case exactly as in my patent referred to-namely, the cord isplaced against the tongue of the cord-holder O, with the covering-strip doubled over the cord, and with one edge of said strip in each of the grooves above and below the said tongue, While the fabrics to which the covered cord is to be stitched ai'e placed one belowand one above the holder, with their edges in line with the edges of the cord-covering strip, all as set forth and shown in my said patent.

The cord-holder is secured to the sewingmachine table in front of the feed, and the presser-foot A is secured on the vertically-reciprocating arm A, directly over the feed and parallel with the needle-bar, (shown in dotted lines at N,) so that the said presser foot reciprocates alternatelywith every plunge of the needle n, bearing down on the fabrics just before the needle carries the thread through.

In my patent already referred to I used a presser-foot provided with a groove on the under side, so that it would hear down on the fabrics equally on both sides of the cord-ridge just before the needle carried the thread through, and thus secure uniformity in the distance between the cord and the seam throughout their length, and perfect evenness in the protrusion of the cord when the seam was turned. In the present case I insure a like result by grooving the bearin g surface of the feed, which receives, secures, and guides the corded fabric in a similar manner whether I use a grooved presser-foot, as in my said patent, or a foot flat on its under surface, as shown in the present drawings, and I wish it understood that I may use either form of presser-foot in connection with my grooved feed, and'a-lso that-I may use a feed-wheel or a two-motion, four-motion, or any other style of feed, so long as the bearing-surface of said feed is grooved, as described.

My improvement, like the paten ted invention already described, upon which it is based, is especially designed for heavy cording, particu larly in the manufacture of carriage-cushions, and in enameled cloth and leather working, and heavy fabrics generally, as in the manufeature of upholstery, and is intended to be applied to ordinary sewing-machines employed for these classes of work by the simple substitution of my feed for those provided in said machines, and the addition of my attachments thereto.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In combination with the presser-bar, needle-bar, and presser-foot of a heavy-work sewlug-machine, a work-feed having a continuous roughened depression or groove extending the entire length or bearing-surface of the feed, the edges of the said depression being parallel throughout their entire length, substantially as shown and described, and for the purpose set forth. I

2. The combination of the presser-bar, needle-bar, and presser-foot of a heavy-work sewing-machine with a work-feed having a continuous roughened depression orgroove ex- 2 tending the entire length or bearing surface of the feed, the edges of the said depression being parallel throughout their entire length, and with a cord-holder located in front of the feed, substantially as shown and described, and for the purpose set forth.

3. A sewing -machine work feed having a continuous roughened depression extending the entire length or bearing-surface of the feed, the edges of the said depression being parallel throughout their entire length, substantially as shown and described, and for the purpose set forth.

In testimony that I claim the foregoing I v have hereunto set my hand this 4th day of 40 November, 1881.

ALONZO LOBDELL.
